Bayesian Robust Quantile Regression

  title={Bayesian Robust Quantile Regression},
  author={Mauro Bernardi and Marco Bottone and Lea Petrella},
  journal={arXiv: Methodology},
Traditional Bayesian quantile regression relies on the Asymmetric Laplace distribution (ALD) mainly because of its satisfactory empirical and theoretical performances. However, the ALD displays medium tails and it is not suitable for data characterized by strong deviations from the Gaussian hypothesis. In this paper, we propose an extension of the ALD Bayesian quantile regression framework to account for fat-tails using the Skew Exponential Power (SEP) distribution. Beside having the $\tau…

On the Lp-quantiles for the Student t distribution
Abstract L p -quantiles are a class of generalised quantiles defined as the minimisers of an expected asymmetric power function. For p = 1 and p = 2 they correspond respectively to the quantiles and

Lp-quantiles represent an important class of generalised quantiles and are defined as the minimisers of an expected asymmetric power function, see Chen (1996). For p = 1 and p = 2 they correspond
General Quantile Time Series Regressions for Applications in Population Demographics
The paper addresses three objectives: the first is a presentation and overview of some important developments in quantile times series approaches relevant to demographic applications—secondly,


Automatic Bayesian quantile regression curve fitting
This paper uses regression quantiles to create Markov chains for the estimation of the quantile curves and uses approximate Bayesian factor in the inference, which extends the work in automatic Bayesian mean curve fitting to quantile regression.
Bayesian adaptive Lasso quantile regression
Recently, variable selection by penalized likelihood has attracted much research interest. In this paper, we propose adaptive Lasso quantile regression (BALQR) from a Bayesian perspective. The method
On Bayesian Modelling of Fat Tails and Skewness
We consider a Bayesian analysis of linear regression models that can account for skewed error distributions with fat tails.The latter two features are often observed characteristics of empirical data
Posterior Consistency of Bayesian Quantile Regression Based on the Misspecified Asymmetric Laplace Density
We explore an asymptotic justication for the widely used and em- pirically veried approach of assuming an asymmetric Laplace distribution (ALD) for the response in Bayesian Quantile Regression. Based
Bayesian Semiparametric Modelling in Quantile Regression
We propose a Bayesian semiparametric methodology for quantile regression modelling. In particular, working with parametric quantile regression functions, we develop Dirichlet process mixture models
Gibbs sampling methods for Bayesian quantile regression
This paper considers quantile regression models using an asymmetric Laplace distribution from a Bayesian point of view. We develop a simple and efficient Gibbs sampling algorithm for fitting the
Bayesian Semiparametric Median Regression Modeling
Median regression models become an attractive alternative to mean regression models when employing flexible families of distributions for the errors. Classical approaches are typically algorithmic
A generalized class of skew distributions and associated robust quantile regression models
This article proposes a generalized class of univariate skew distributions that are constructed through partitioning two scaled mixture of normal (Gaussian) distributions. The proposed distributions
High dimensional structured additive regression models: Bayesian regularization, smoothing and predictive performance
Data structures in modern applications frequently combine the necessity of flexible regression techniques such as nonlinear and spatial effects with high-dimensional covariate vectors. While
The Bayesian Lasso
The Lasso estimate for linear regression parameters can be interpreted as a Bayesian posterior mode estimate when the regression parameters have independent Laplace (i.e., double-exponential) priors.
